IRONING MACHINE.

Application filed June 26, 1924. Serial No. 722,434.

This invention relates to ironing machines and has for its object to permit the pressing means to be removed from the heated surface in case a foreign body, such as the hand of the operator, gets caught between the heated surface and padded. roll or other pressing means holding the goods against the hot surface. 7

Ironing machines are usually provided with a heated surface, generally a cylinder, and pressing means, such as apadded roll, for holding the goods against the heated surface as it passes through the machine. Manual mechanism is usually provided for separating the cylinder and pressing means in order to withdraw or insert the work. With the usually mounted bearing such mechanism cannot be separated sufiiciently to prevent crushing the hand and arm of an operator if accidentally drawn in. v 7

According to this invention, separation of the pressing means and cylinder more than the normal distance automatically. releases the pressing means, such as the roll, permitting the hand to be withdrawn before it is injured. To accomplish this result in the embodiment illustrated a latch releases the spring pressing the padded roll against the heated surface and allows said padded roll to be raised as much asdesired and quickly removed. Release of one roll may also release others.

In the accompanying drawings:

Figure 1 is an end view of the preferred form of my invention,

Fig. 2 is a section on the line AP--2 of Fig. 1,

Fig. 3 is an end view of another form of the invention, and

Fig. 4 is a section with the right end taken. on the line 2-2 and the left end taken on the line 2"2 of Fig. 3.

A feed table holds the work as it is fed between the heated cylinder 11 and the padded rolls 12, 13 and 14:, said rolls being,

mounted as is customary in bearing blocks 15, slidable in guideways 16 in the end frames of the machine. The projection 17 is connected with some pedal mechanism (not shown) for turning the'cams 18, 19 and 20 in raising' or lowering the padded rolls from the cylinder. For pressing the padded rolls 12 and 13 against the cylinder and work a bridging element 21, pivoted at 22, extends across the guideways 16 thereof and springs 23 are mounted between the bridging ele ment 21 and the bearing blocks lint-ending to press the padded rolls downward against the cylinder. In the embodiment illustrated, the bridging element extends over the bear ing blocks and guideways of two of the rolls. A latch 24- pivoted at 25 retains the bridging element in position and prevents the springs from forcing it upward. An extension 26 on the latch engages the bearing block 15 of the padded roll 12 so that when this block and its padded roll are raised more than is possible by the foot operated cam the extension 26 releases the latch, and with nothing to retain the bridging element 21 in position the springs 23 force it upward or may throw it over so as to completely uncover the guideways and allow the roll or rolls to be removed from the machine.

. In Figs. 3 and t is illustrated a modification in which a separate safetylatch mecha nism is provided for each of the rolls 12. and 13. In this embodiment, the bridging element 30 is pivoted at 31 to the end frame of the machine and the latch 32 is pivoted at 33. The actuating extension 3 1-, instead of being integral with the latch is separate, being pivoted at 35 and provided with a cam surface which engages the latch and moves itto the left as the lever and bearing block are raised more than the usual predetermined amount. As latch 32 is moved to the left; thelock pin 36 is moved suiiiciently to release the surface 37 of thebridging element, thereby enabling the spring 38 to swing the bridging element about its pivot 31 and uncover the guide ways, enabling the rollers to be withdrawi'i, as well as the compression of the springs 38 released. in operation the raising and low ering of the rolls from the cylinder may be any convenient amount found desirable, and about has been found more than enough to include even the thickest materials to be ironed. An operators hand is usually much hicker than so that in event the hand is caught between the roll and heated cylinder it will cause either or both ends of the roll to be raised more than their normal amount, with the result that the safety latch is released and the compression spring swings the bridging element enough to not only release the springs but to uncover the guideways and enable the padded rolls to be withdrawn whereby the operator may then withdraw his hand before it is crushed or seriously burned.

I claim:

1. In an ironing machine, the combination with aheated surface, of a plurality of padded rolls, means for pressing said rolls against said surface, and a latch mechanism for releasing said means for the plurality of rolls on separation of the surface and one of the rolls more than a predetermined amount.

2. In an ironing machine, the combination with a heated cylinder, of a plurality of padded rolls for engagement therewith, springs for pressing the ends of each roll against the cylinder, means for separating said rolls and cylinder during operation of the machine,a member above said rolls for compressing the sprin s of the several rolls, a latch for retaining said member in operative position," and means for releasing said latch and member on separation of the first roll and cylinder a predetermined amount.

3. In an ironing machine, the combination with a heated surface, of a plurality of ironing rolls, means for confining said rolls on the machine in yielding engagement ith said heated surface, means for moving said rolls a predetermined distance away from said heated surface to accommodate the insertion of different articles to be ironed, and means operative upon the movement of one of said rolls beyond said predetermined distance to release said vconfining means to permit the removal of said rolls from the machine.

4-. In an ironing machine, the combination with a heated surface, of a plurality of ironing rolls, means for pressing said rolls into yielding engagement with said heated surface, an actuating member for moving saidrolls a predeteri'nined distance away from said heated surface to accommodate the insertion of difi'erent articles to be ironed, and means operative upon the movement of one of said rolls beyond said predetermined distance for releasing said pressing means.

5. An ironing machine comprising a heated surface, a plurality of guideways open at one end, a plurality of ironing rolls having bearings slidably mounted in said guideways to permit said rolls to be moved toward and away from said heated surface, a bridging member confining said bearings in said guideways, and means responsive to the movement of one of said rolls beyond a predetern'iined distance to release said bridging member and thereby permit the remo al of said rolls.

(3. An ironing machine comprising a frame, a heated roll journaled in said frame, a plurality of open guideways on each end of said frame, a plurality of ironing rolls having bearings slidably mounted in said gu'ideways to permit said ironing rolls to be moved toward and away from said heated roll, means including a bridging member pivoted to said frame and spanning said guideways to force said ironing rolls into yielding engagement with said heated roll, an actuating cam engaging said hearings to move said ironing rolls away from said heat ed roll to accommodate the insertion of the different articles to be ironed, and latches engaging said bridging member having portions engaging the bearings of one of said ironing rolls and responsive to the movement of said roll beyond a' predetermined distance to release said bridging member and thereby permit the removal of said iron ing rolls.

Signed at New York City, in the county of New York and State of New York, this 24th day of June, A. D. 1924.
